Introduction

The UCC AI is required for large higher voltage CMM systems which may require motor voltages in excess of 80 V or motor currents in excess of 10 A. These voltages and currents are not supported by current Renishaw SPA products. The UCC AI provides the interface between the CMM controller and a third party servo power analogue amplifier (which provides power to the CMM motors).

Features

  • Supports third party servo power analogue interface amplifiers
  • ± 10 V differential analogue SPA command
  • SPA control I/O
  • The UCC AI can automatically adjust the supply voltage to encoder readheads (to compensate for long scale cables)
  • Up to four CMM axes can be handled by the UCC AI
  • Up to five CMM axes can be handled by a dual UCC AI setup
  • Some 3rd party temperature compensation boxes can be interfaced to the UCC AI using the RS232 interface
  • Probe interface (PICS)
  • MCU interface
  • Supporting incremental and absolute encoders
  • CMM machine input / output, including:

• Air solenoid
• Brakes (for each axis)
• Z-axis crash status
• Travel limit warnings (both inner and outer limits for each axis)
• Air status
• 13 un-committed I/O (6 input and 7 output) that can be customised by the user
